Abstract: ABSTRACT OF THE DISCLOSURE:     The target comprises a target ring arrangement with a frame bounding a measuring chamber and closed at the front and rear by fabric covers said frame carrying on the inside acoustic sensors as well as a surface layer carrying the target image.  In order to produce approximately the same temperature gradient at each point of the target plane a downwardly and upwardly open air circulation space is formed between the surface layer carrying inthe target image the front measuring chamber cover and/or a roof-like cover which at least in the forwards direction projects over the surface layer carrying the target image is provided in the upper edge area of the target ring arrangement.  The sensors have a clearly defined position relative to the reference coordinate system.  To ensure that changes to the sound propagation velocity within the target do not lead to incorrect indications, the group of sensors has at least one more sensor than is necessary for calculating the shot position when the sound propagation velocity is known.

Abstract: METHOD FOR REMOVING NITROGEN   OXIDES FROM A GAS STREAM     ABSTRACT      A gas stream containing nitrogen oxides, such as the tail gas from a nitric acid plant, is treated to reduce the nitrogen oxides content thereof.  The method results in the production of a product gas stream and an aqueous solution of ammonium nitrate.  In a liquid-gas contact apparatus, the gas stream is first reacted, under steady state conditions, in counter-current flow, with an aqueous solution of ammonium nitrate at a pH of about 0.01 to about 0.5.  The gas stream is then further reacted in counter-current flow with an aqueous solution of ammonium nitrate at a pH of about 8.1 to about 8.5; and thereafter in counter-current flow with water, pref-erably slightly acidified to a pH of 6.0 to 6.5.

Abstract: D-3,428     C-3,133 NOISE TOLERANT MULTIPLEX SYSTEM            Abstract of the Disclosure:         A noise tolerant time division multiplex system including a transmitter and receiver, each constructed as a monolithic integrated circuit and interconnected by a serial data wire.  Data as well as power is supplied to the transmitter from a plurality of parallel connected input switches.          The transmitter includes a parallel in/serial out shift register controlled by timing logic and further includes a tri-state driver for generating a three-level serial output signal indicative of the status of the input switches.  The data is generated at a high rate to eliminate any deleterious effects of noise on the system.  The receiver chip receives a regulated energizing potential from the transmitter chip over two additional wires, generates a timing signal from the three level signal and loads the data in binary format into a serial in/parallel out shift register.  When the data is properly positioned in the receiver register the data is transferred to latches which energize appropriate relays to control the direction of rotation of various motors controlling the seats, windows and door locks of an automobile.

The stud includes at least one elongated relatively thin metallic projection from each end of the stud to be welded.  The method and apparatus maintains a current density in a given projection sufficient to disintegrate only a portion of each projection with consequent arc initiation upon contact with the base metal such that the disintegration of a given projection will permit the remaining projections to contact the base metal causing a short to extinguish the one arc which has been initiated and consequent disintegration and arcing of the next tip to strike the workpiece which procedure proceeds randomly from tip to tip until the ends of the stud reach the molten metal pools.  The studs and footpiece for the welding gun are of a configuration to insure proper alignment of the stud with respect to the work-piece while the footpiece of the gun includes means for securing to arc shields properly in place.

Abstract: A B S T R A C T            With known vehicle superstructures of the above kind it has been found that in many cases relatively large amounts of deformation and damage to parts of the floor and walls occur even when the collision is very slight, that the thermal insulation is inadequ-ate and that noises are produced in the sidewalls and floor due to vibrations during the journey.     With the new vehicle superstructure the external forces acting on the sidewall (14) are no longer transmitted directly to the floor (18) but reduced to a minimum level, which in most cases-does not damage the floor (18), by means of a close-fit connection with built-in buffer zone (24). Also, the new design improves thermal insulation and markedly reduces the noises produced in the superstructure during a journey. Furthermore, the parts which have to be repaired can be readily removed and replaced.

Abstract: ABSTRACT  IMPROVEMENTS IN OR RELATING TO THE VALVE TIMING MECHANISMS               OF INTERNAL COMBUSTION ENGINES An internal combustion engine having at least one cylinder with inlet and exhaust valves operated via rocker arms by respective cams carried by a single camshaft.  The camshaft is connected to its drive by an eccentric linkage, the eccentricity of which is varied by a device responsive to engine speed, and is least at high speed. As engine speed falls, increasing eccentricity results in a relative advance of inlet valve closing time and relative retardation of exhaust and inlet valve opening times but little change in the timing of exhaust valve closure.  The lift of the valves may be varied also if the rocker arm axes are movably mounted.

Abstract: ABSTRACT OF THE INVENTION      This invention provides an automated single pass dialy-sate supply apparatus and a method for conducting hemodialysis treatments when the apparatus is used.  The apparatus is of the closed circuit type and provides a pair of cylinders, each equipped with a hydraulically driven diaphragm, which supply fresh dialysate to and remove spent dialysate from an artifi-cial kidney on an alternating time basis;  the improvement resides in the means which sense the difference in time of arrival of the end of stroke of each diaphragm and automati-cally counteract these differences to either maintain or restore synchronization of the instant of end of stroke of each diaphragm in each half cycle of operation.     The hemodialysis treatment method permits operator pre-setting of the desired ultrafiltrate removal rate and insures maintenance of that preset rate throughout the hemodialysis treatment period.

Abstract: ABSTRACT         An electrophotographic printing machine which has a cleaning station for removing particles from a photoconductive surface.  The cleaning station includes a magnetic transport for moving a cleaning material into contact with the photoconductive surface.  The magnetic transport is electrically biased to a polarity and magnitude sufficient to attract the particles from the photoconductive surface to the cleaning material.   An electrically non-conductive member, positioned close-ly adjacent to the magnetic transport, is electrically biased to the same polarity as the magnetic transport with the magnitude thereof being greater than the magnitude of the electrical bias applied to the magnetic transport.  In this way, particles adhering to the cleaning material on the magnetic transport are attracted therefrom to the electrically non-conductive member.
